Application iiledA April 1'7, 1905. Serial No. 255,963.

Be it known that l, AUGUST DE Tum", a citizen of the Republic of Switzerland, residing' in Philadelphia, Pennsylvania, have invented certain Improvements in lnhalers, of which the 'following is a specification.

One object of myinvention is to provide an inhalcr with improved means for breaking an anesthetic containing and frangible capsule after the latter has been properly inserted in the inhaler, it being' further desired to provide means for properly directing and distributing' the liquid delivered from said capsule upon absorbent material suitably placed within the inhalcr. rl`hese objects lv attain as hereinafter set forth, reference being' had to4 the accompanying drawings, in which* Figure 1 is a perspective View of my improved inhaler, and Fig. 2 is a sectional elevation showing' the interior construction of the inhalcr illustrated in Fig. l.

ln the above drawings, A is a metal tube made in two portions e and a at right angles to each other. To one end of the part c is connected a face-piece B, consisting of a pneumatic rubber pad and a supporting-cone therefor. The opposite end of the said part a is provided with a tube c, fitting within it and having a cap C, there being' one or more openings in said tube for regulating the supply of air.

Projecting into the tubular part a in the `line of the right-angled portion c/ isatubular guide a2, and there is in addition a tube d, carried by the tube c, which may in one position of this latter form a continuation of the guideway c2. The lower end of the tubular part u.' is provided with an enlarged neck a for the reception of an air-bag l), while there is within said portion c aremovablefranie d, formed of spirally-wound wire, upon which is carried a body of absorbent material d. such as cotton or gauze. Forming part of the frame Z is a removable cap ai, having an opening covered with a piece of gauze ai.

Extending' across the tubular portion c above the frame l is a de'l'lector E, preferably consisting' of two plane portions connected along a common edge and placed to one side of the center line of the guideway formed by the tubes a2 and c. Between the end of the be used.

' lar portion n/ in lines preferably parallel with the surface of the piece lil.

lifhcn .it is desired to provide the inhalcr with anesthetic, the capsule, which is `frangible and usually of the form shown in dotted lines at F, is inserted tl'irough the g'uideway c, so that its elongated end strikes the inclined surface of the de'l'lector lC. lf the capsule be 'forced farther into the inhalcr, said end engages the stop e, so that it is broken, and the liquid anesthetic is directed by the dellector to the tubular body of absorbent material. ,lt will be seen that this directing' of the liquid is due to the .shape of the piece E, which by del'lecting it toward the sides of the tu bular portion 1t prevents its Yfalling' straight through the open central portion of the 'frame (l. As will be understood by those skilled in the art, the amount of air entering the inhalcr is regulated by the operation of the cap U in the well-known manner.

l claim as my invention--A l. An inhalcr haring a guideway 'for ananesthetic-containing' fiangible capsule, and. means Vfor automatically breaking' said capsule within the inhalcr when said capsule is forced into the guideway, substantially as described.

2. The combhiation in an inhalcr of a tubular gl'lideway, apiece within the inhalcr iuclined to the line of the guideway and placed to engage and break the end of an anestheticcontaining frangible capsule forced into the guideway, su bstantially as described.

25. '.llhe combination in an inhalcr of a tube containing` a body of absorbent material and having an opening', and a defieetor having a surface inclined to the line of said opening and placed to engage the end of an anestheticcontaining' fral'igible capsule `forced into the opening', said delleetor also directing' liquid from said capsule to the absorbent material, substantially as described.

4t. rlho combination in an inhalcr of a tubular guideway, a piece having' its surface inclined to the line of said guideway, and a stop adjacent to said surface, said parts being' arranged to engage and break the end of a Yfrangible capsule Aforced into said guideway, substantially as described.

5. The com bin-ation in an inhalcr of a tubular guideway. a piece having' its surface inclined to the line of said gnidr-nvay, and a stop adjacent to said surface, said parts being' arranged to engage and break the end of a material, with a stop adjacent to said piece placed to coact therewith to break the point of a frangible capsule forced into said guideway, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
